usefullmprovexnents in Lanterns, of which the following is al specification.

invention relates to lanterns and has for its object to provide a lanternhaving incandescent light-giving. mechanism eflected through the delivery of hot gas, as gasolene or, kerosene, and the burning of the same within mantles of, usual construction.

To this end L provide a lantern having a Receiver for the oil and means directly in said receivcr-ior compressing air within the some upon the body of the oil, together with means for conducting said oil into the lam torn and a specially devised generator mechanism for turning said oil into gas and delivering-the same to the burner and mantles.

'T'he full'objects and advantages of my invention will appear in connection with the detailed description thereof and are particularlypointed out in the claims.

In the drawings, illustrating the application of my. invention in one form,--Figure 1 isan elevation view ofa lantern embodying my ixn 'irovements. Fig. 2 is a sectional elevation view. taken on a different line from 53g. 1, Fig. 3 isa sectional plan view of e base or; oil: container. Fig. 4 is an en lar'ged sectional View of the pumping IIlGCllanisin.

As illustrated, my lantern comprises a base 10 which is formed of sheet metal and provides an air-tight reservoir 11 into which gasolene or. kerosene may be introduced through an inlet 12, closed by plug 13.

Upon the top platform, 1d of the base 1O is rigidly secured a standard 15 in the form of a pipe, which standard is provided with a control valve 16. Thestandard 15 is a hollow pipe which communicates at its top with a bow-shaped pipe member 17. from which dcpendburner tubes 18 and 19 having thereon mantles 20 of any well'known construction. The pipe standard 15 has connected therewith below the bow-piece 17 an air-tube 21, which air-tube extends downwardly through a plate 22 secured to the standard'loby means of a hub 23 and setscrew, 2 1. The air for admixture with the oil is supplied through tube 21. If additional air outsidethe generator is deemed advisable it may be obtained through a damper-controlled aperture'25 in plate 22.

The plate 22 forms a support for a lantern globe 26 of ordinary construction. The top of the globe 26 is supported in a sheet metal hood 2? carriedby a cap 28 which is held in position upon a bolt 29 rigidly connected withthe bow-piece 17. Cap, hood, and globe 26 are. held rigidly assembled by means of a hand-nut 30 threaded upon the top of bolt. 29. a

The means for producing air pressure upon the oil within reservoir 11 comprises a casing 31 permanently secured across the chamber 11. One end of casing 31 is closed by a plug 32. The plug 32 is provided with a screw-threaded seat 33 into which may be screwed the threaded end 34 of an ordinary air-chamber 35, the cap 36 of the air-chamber closing the other end of casing 31. The air-char'nber is thus removably held within casing 31. The inner portion of the seat cavity 33 is connected by a duct 37 with a cavity 38 in plug 32, in which is threaded a screw-plug 39. From the cavity 38 a duct yatented Feb. 9, 1915.,

40 leads into the interior of reservoir 11, Y

The scrcw-plug 39 may be caused to seal up duct 40 or open the same to cavity 38,

as may be desired When the pump is employed for applying pressure in chamber 11, the pump will be operated through handpicce 41 in the usual way, duct 40 having been previously uncovered. After smlicicnt prcssurc has been applied within the reservoir 11. the plug 30 is screwed up so as to close duct 40. and a threaded seat 492 on a hand-piece 41 is screwed on to a threaded extension 43 of pump-cap 36 to hold the piston 4A in position in the pump barrel.

The pump is therefore carried at all times in the lantern, and yet is so protected that the gasolene or kerosene cannot reach the v should become necessary or desirable.

piston 44:. if it did it would quickly destroy the eiiiciency of said piston because of the corroding, cutting action of kerosene or gasolene. At the same time the pump may be readil withdrawn for repair, if tilt}; small tube 45 leads from the bottom of reservoir 11 into-the bottom of stand-pipe 325 below valve 16, through which air pressure upon the surface 46 of the oil in reservoir 11 forces such oil into stand-pipe 15 and through valve 16, where the gas is generated and mixed with air from pipe 21.

A separate casing 47 extends within rewervoir 11 and is closed from the outside by a stopper 48 upon which is secured a burner member so. A reservoir 50 Within casing i? is kept filled with alcohol, and when it is desired to light the same, the lighted burner i9 is thrust through the opening 25 to heat the pipes 15 and 17 suiiicientiy to generate gas when the valve 16 is opened to permit inflow of fuel oil.

The operation and combination of my lantern have been very fully given. By use of the pump 35, air within reservoir 11 is compressed upon the surface 46 so as to produce a high/pressure. It is noted that the filling plus 13 is so positioned that the surface 46 will always be lower than the open- With the proper pressure upon the oil surface 46, and

' after the pipes have been heated by the alcohol pressure, as above pointed out, the valve 16 is turned to the desired extent and the aforesaid pressure causes the fuel oil to rise through tube 45 and valve 16 upon the heated walls of the generator mechanism. The gases generated and mixed with air coming from tube 21 travel throus'h the tubes 18 and 19 and are burned Within the mantles Q0. ,Q'i inor a brilliant light. The burning oi. these gases heats tubes 18 and 19 and bow-tube 1'? so that an extremely ellicient carburetion accompl shed.
